Letters Patent No. 73,841, dated January 28, 1868.

IMBROVEMENT Ill TRUNK-LUCES.

TO ALL WHQM IT MAY CONOERN:

Be it linown that l, GEORGE RUPPEL, of Harlem, in the county'and State of lew York, 'have invented a new and improved Trunk-Lock; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the, art to malte and use the saine, referenceibeing had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a rear view of my improved lock.

Figure is a rear view of thc removable portion of the same.

Figure 3 is a rear view of the removable portion, the outer or back cover beingI removed.

Figure 4 is an inner or front view oi' the stationary portion ot' my improved lock.

Figure 5 is a vertical'central section ofthe lock, the plane of section' being indicated by the line x z, iig. l.

Similar letters of reference indicate corresponding parts.

This invention relates to a new kind of lock, which is intendedto be used on trunks, satchels, carpet-bags, and wherever a folding lid is to be locked to a stationary or also folding body.

The invention consists in the Ause of a removable circular lock, which is to be connected with a circular plate, that is attached to the stationary part of the trunk, said lock having a central bolt, which, when inserted through an oblong hole in the aforesaid plate, and then through one in a plate attached to the cover, will securely connect the two parts ot' the trunk or bag, and also the lock to the same, after t-he'loelc is turned onequarter around. Y |lhe bolts, v.'hieh'are arranged in the lock, are, by means ci' suitable springs, thrown'into holes provided in a llange projecting from and around the circular plate, said flange lapping over and around the loc-k, and the main or central bolt has a T-shaped head, which is passed through the oblong slot in thegplate, and which, when the lock is turned, securcsthe lock to the plat'e. Another similar head, at the further end of the central bolt, secures, in a similar manner, the lid to the body ofthe trunk or bag. Taremove the lock and open the trunk, the small bolts must be pushed out of therecesscs in the plate by means of a key havingT pins, the latter itting throughholes arranged in the rim of the lock'. These pins, if n ot of the exactly correct length, will either 4not b e long enough to push the bolts out, orthey will betoo long, and will push the bolts into recesses provided in the flange ot' theplate, at the opposite side, which arrangement is easily obtained by the circular form ofthe lock. When the bolts are pushed out ot' the flange, the lock can beturned until the head of the central bolt is in line with the slot in the plate, and the lock can then be taken oi?, and the trunk or bag is open. v y v i i A represents a circular metalplate, secured by means of screws, or otherwise, to the body or lid of a trunk or carpet-bag. It has in its centre an oblong slot, a, as isclearly seen in figs. 1 and, and is, at ,or near its circumference, provided with a flange, Z1, which projects towards the front, as shown, (fig. 5.) B is la circular cup, or a round plate with a flange around it, the inner diameter of which is equal tort/he outer diameter of the flange b. It' desired, the outer diameter of the flange on B'may be made equal to the inner diameter of the flange b.' In the centre4 of the cup B is a stem orlce'ntral bolt, G,- wliich has a T-shaped head, c, which, when the two parts A and B are brought together, will fit through the slot a, and when, then, the part B is turned, it will stand as in fig. 1,'and will connect the parts together. Within the cup B are arranged three or'more or less bolts, D D, which vare arranged parallel with one diameter of the cup, and all parallel with each other, all being as long as the distancein the flange I: of those points which are touched by the bolts. By means of spiral or other suitable springs, UZ d, which are guided in suitable grooves in the cup, the boltsD are thrown towards the angeof the cupB. Each of these bolts, D, has'a lip, ve, which, as is seen in tlg. 5, is under one of a number of'small holes, f, that are arranged in the rim of the cup, the lip being near that end of each bolt which is thrown out bythe spring. v It will be clearly understood that, ywhen the cup or lock B is detached, the ends ofthe bolts D are, by the springs el, thrown against the inner side of the flange of the cup. To t the cup to the plate A, its -lange must first be cleared from the bolts, so that it can be tted over the flange b. For this purpose, a key, E having as many pins, g, as there are bolts and holes, j', is appliedto the cup. The pinsg are tted lthrough the holes f, sc that they touch the lips c, and the key is then pressed'in so as to push the bolts back towards the opposite side. The cup can now be attached to the plate A, and the key removed. The cup is then turned until the ends of the bolts D are foroedby thespring el into holes, h z, provided in the llange b,`as is clearly shown in, g.'4. At the same time, the two parts A and B are also connected by the central bolt C. The saine may, at its extreme end, have another head, which its through anoblong,r slot, provided in the lid or opposite part of the trunk or bag, as is indicated by red and blue Alines in iig. 5, or the head e may be fitted directly through the .slot in the plate A, and through that in the lid. Opposite to the holes i, are holes i; arranged in the flange b for the-purpose of receiving the other ndsof the bolts, in case it is attelnpted to open the locl ,\\'ith a. false key, so that when the pins on such a false key are too long, the vbolts may be pushed into theholes z', as will be understood from hg. 5.

For unlocking, the' bolts D must be elear'ed from the flange IJ by'means of the key E, and the cup B turned until the head c is inline with the slot a, which is ascertained bymeans of a stop,j, arranged on the plate A, said stop also preventing the, turning of the cup when locked. The cup-can then be taken off, and the trunk or bag y`will be open, and cannot be'locked again without the use of the cup.

It will be observed that a kcy-hole and a, lining for the same are not neededwhere this lock is used, which is a great saving in the doost of construction of trunks, satchels, Snc. .The lock Acan be made of suitable dimensions, and can, on account of its simplicity, be madev very small and light. t A' f,

If desired, the head, c, of the bolt may be dispensed with, especially if such a head is already on the outer end ofthe bolt to connect the licl to thevtruiilr. The invention can also be used on doors and other places to protect and cover-the key-holes. i

y I claim as new, and desire to secure by Letters Patent-:- 1 A The manner, herein shown and described, of attaching the cup B to the plate A, and to the two parts of the trunk or bag, by Ineens of sliding-bolts D D, and a central-headed stem, C, all made and operating substantially as herein shown and described. v GEORGE RUPPEL.
